BO'l'TL E-STOPPER.

SPECIFICATION forming part of Letters Patent No. 232,613, dated September 28, 1880.

Application filed August 24, 1880.

To all whom at may concern:

, Be it known that I, PUROHES MILEs, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Bottle-Stopper, of which the following is a specification.

Figures 1 and 2 are vertical sectional views of my improved bottle-stopper, showing it respectively contracted and extended lengthwise. Fig. 3 is a perspective view of the bandle and cap-piece of the stopper. Fig. 4 is a side view of the pin for stretching the stopper.

This invention has for its object to make an internal bottle-stopper removable from the bottle.

Internal bottle-stoppers are, of necessity, so constructed that they cannot be expelled from the bottle by even the strongest pressure from within. Hence, they are not removable from the bottle by even the strongest'pull from without. These considerations have thus far induced manufacturers to so construct internal stoppers, especially those having rigid suspension-bails, that they were not removable from, and therefore permanent fixtures within, the bottles. As the stoppers become old and soiled their removal from the bottle is, however, positively desirable.

I have invented an extensible stopper, which, when extended lengthwise, is capable of lateral contraction sufficient to permit its removal from the bottle.

In the drawings, the letterArepresents the bottle-stopper; B, its bail or handle, of suitable form and construction, and hinged or rigidly fastened to the stopper. Said bail serves to hold the stopper suspended in ,the bottle when the same is open.

(3 is a bottle which the stopper is intended to fit and close from within.

The stopper in the illustration is shown to be made of three parts or sections, a, b, and d. The part a is a metal cap, slightly conical, with downwardly-projectin g prongs or springs, as shown in Fig. 3, and with an apert1ire,e, in top. 11 is a conical or other shaped plug or plate inserted into the cap from below, as shown in Fig. 1; d is an envelope, of indiarubber or equivalent material, placed around the lower part of the cap (t, so as to embrace (No model.)

its sides and constitute the valve-surface of the stopper, said rubber envelope extending, also, beneath the plug I), so as to retain the same in place by its spring action. The elastic or spring property of the envelope (1 causes it also to retain its position on the cap, as in Fig. 1.

When the stopper is to be inserted into or taken from the bottle a pin, D, is introduced through the holecor other opening from above, and pushed down so as to reach the plug 12 and push the same part way out of the cap and distend the rubber cl lengthwise, as shown in Fig. 2. Thus the stopper becomes elongated, and the prongs of the cap lose their inner support, so that the entire stopper can be readily passed through the narrowest part in the neck of the bottle. As soon as the pin.Dis disengaged from the stopper the rubber d carries the plug or plate I) back into its proper position in contact with the cap, as in Fig. l, in which position of its parts the stopper will be incapable of passing through the neck of said bottle.

In order to permit the convenient handling of the stopper in its longitudinally-extended position, I provide the upper part of the pin D with a projecting handle'arm, f, having a notch, 9. (See Fig. 4.) When the notch g is in line with the upper cross-piece, h, of the bail B the pin D is held in place by thepress ure of the rubber cl, and is thereby temporarily united with the stopper, holding the same distended lengthwise, as in Fig. 2.

Many modifications in the construction of the longitudinally-extensible, and thereby laterally-contractable, stopper, may be devised without departing from the spirit of my invencap a, plug 1), and rubber envelope d, the cap handle B, rigidly secured thereto, and made having aperture 6, substantially as herein longitudinally extensible, to be removable I0 shown and described. from the bottle when so extended, substan- 3.
